Mine are 3mm id , so it can wick pretty well and have a nice amount of cotton it works well for me this way , even using the SRv4 with a similar build works just as well , i use a spaced build for working better for TC vaping on my dna VT 75w , and TCR on Tesla nanoI'm just curious, does using a spaced coil versus a micro coil make a difference you think? Because I've been using a micro coil build, 26 gauge Kanthal to 1.4 ohm..
